Compare two saved acoustic traces position by position to see agreement, disagreement and uncertain taps. HOW IT WORKS 1. Mark at least three positions, calibrate for the wall, and save two traces using the same positions. 2. Open History, tap Compare, select the passes, and confirm matching positions and calibration. 3. Reverse the second pass if needed, inspect each position, and share the comparison. An illustrative example is available. Listen, Trace, calibration and the multi-pass survey composer remain available. The composer now opens from History so it does not cover the bottom navigation. WHAT TO KNOW Repeatability does not prove a stud or a safe mounting point. Acoustic taps cannot identify wiring, pipes or other hidden hazards. Independently verify before drilling. Different trace lengths are rejected; low-confidence taps and edge classifications remain uncertain even when labels match. iPhone and iPad.
